In order to promote cultivated land protection and optimize cultivated land utilization pattern in the Pearl River Delta, we further deepened the connotation of cultivated land use transition. Taking the Pearl River Delta city groups as an example, we constructed an index system from three dimensions of structure, efficiency and function. The entropy weight method, ArcGIS spatial analysis and grey correlation analysis were used to explore the spatial and temporal evolution characteristics and influence factors of cultivated land use transition in 9 cities of the Pearl River Delta. The results show that:(1)the diagnosis of regional cultivated land use transition can be measured from three aspects of structure, efficiency and function;(2)the composite transition level of cultivated land in the Pearl River Delta increased; the difference of the composite transition level among cities was obvious but decreased;(3)the cultivated land use transition level in the Pearl River Delta had a core-periphery structure in space, and the transition level of central cities was low;(4)the scores of cities in the 3 levels of structural, efficiency and functional transition were uneven, with differences in the strengths and weaknesses of transition; the efficiency transition index of Shenzhen increased by 293.12%, the structural transition index of Guangzhou decreased by 19.76%, and the functional transition index of Zhongshan decreased by 20.69%;(5)the urbanization rate, the GDP per capita, and the fixed asset investment per capita had a significant impact on the transition of cultivated land use. In conclusion, the transition of cultivated land in the Pearl River Delta was transforming in the direction of optimization, but the differences in transition between regions could not be ignored. Demographic and social factors played the greater role in promoting the transition of cultivated land in the Pearl River Delta.
